I know that blades have a significant YMMV factor...but I must say I continue to be pleased with the performance of Derby Extra. It seems these blades were once the sweetheart of many wet shavers but then fell out of fashion. The scorn of many. A few years back I did a personal blade trial with many blades and ended up buying a 100 pack of Derby Extra and they are a daily go-to for me. Any others out there that enjoy Derby Extra?
